' Specification of Letters Patent.

To all warm, u ma concern." t

Be it known that 1, CHARLES E. GODLEY, a

. citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, I Improved Lamp, of which the following 15 a specification.

This invention relates to lamps espec ally adapted for automobiles and other vehicles, and its object is to provide a construction which, when mounted on a vehicle, Willnot rattle; Will be. strong; will be attractlve; and'can be readily opened for cleaning.

This invention consists in a lamp comprising a body, a reflector and a ring sup porting the lens, together with springs mounted between the body and the reflecterin such a manner that the reflector will be pressed against the lens to prevent both from rattling, and to prevent the entrance of air and moisture. I

- It further consists in the use of bayonetjoints in connection with both the reflector and the cap to unite them with the body.

In the accompanying drawings Figure 1 is a side elevation and Fig. 2 a vertical longitudinal section of this improved lamp. Fig. 3 is a front elevation of the lamp a portion of the lens-support1ng ring being broken away. Fig. L is a side elevation of the front portion of the lamp with parts of the lens-supporting ring broken away in order to show the interior arrangement. Fig. 5 is a sectiolron the line 5-5 of Fig. 1. Fig. dis a front elevation of the lamp with the lens-supporting ring removed. Fig. 7 is a side elevation of a small portion of the lamp. Fig.8 is an elevation of the front endof the body. Fig. 9 is a side elevation of a small portion of the body showing one of the springs. Fig. 10 is a rear elevation of a modified form of lamp. Figs. 11, 12 and 13 v are sections on the lines 1111, 12-12 and 13-l3 of Fig. 10 respectively.

' Similar reference characters reler; -to like parts throughout the several views.

The body 1 of this lamp is substantially parabolic and has a reinforcing device 2 fitted to it and secured in place by means of rivets 3. See Fig. 2. An insulating member d Within this reinforcing member supports the rrods 5 by which this lamp may connect to a current source and to which are connected thewires 6 that lead to the base 7 of thalamp '8. This lamp maybe revohave invented a new and lubly and frictional ly mounted in sdosrair tially the focus of the parabolic reflector 9. The parts thus far dcscrilmd form no part of this invention.

Referring to l igs. 5, S and 9., the body l is shown formed with a cylimlrical portion 10 and an inwardly turned flange ll, which carries the headed posts lat and the springs 12, held in position by the bolts 13. In the flange 11 are three holes 15 for the stop pin 16, three holes being drilled and lapped so that the pin can he inserted, no matter how the reflector is inserted.

The body of the reflector is parabolic, and at its edge it is provided with a grooved rim 3.? to receive the cord. or .llOU 18 which is pressed against the lens, and therefore, transmits pre urc w. the supporting; ring and prevents rattling. Just outside of the grooved rim a bnchwarrlly extending;-

cylindrical portion 19 and at the rear edge of this cylinder is a radial llang'c 20 having" slots 22 to permit the relative circular move ment of the posts 14, the hey-hole slots to receive the bolls 1.3, and almle to permit the entrance of the StOPPlI1 l6.

lVhcn it is dr-sired mount the roll ..'t -r on thcbody,tl1c lamp base '7 is loser-(ml in the. opening in the rear cud of the .rcl'lcctor and the reflector is inserted in the body lo about the position shown in Fig. 9 with the bolts 13 passing through the enlarged lfl'lllS of the slots 23, and the posts l-il. through the slots 22, the reflector resting against the springs 12. The reflector is then pressed i -1c]; into the body, compressing the spun 5 152 so that the heads oi. the bolls ll; will extend beyond the face of the flange 2!). as shown in Fig. 7, sullicicnlly to permit the rcllcctor to be turned and thus relatively carry the bolts 13 to the opposite ends of the slots 93, as shown in Fig. (5. The locking pin 16 is then passed through a hole in the flange 20 and scremrd into one of the holes 15 in the flange 11 of the body thus holding the reflector from turning in the body. The bolts 13, posts lat and holes 15 are evenly a d exactly spaccdso that there is no 'difliculty in positioning the reflector.

The lens :25 is of any desired curvature, and is mounted in a hollow supporting ring formed of two thicknesses,'ns shown in Fig. 5. The outerthickness 26 is substantially semi-circular thickness is formed of three cylinders 23',

n 'crossscction while the inner 28 and 20, joined by radial flanges 30 and 31. In Fig. 3, the front portion of the part 26 is broken away to show the flange 31 which is provided with keyhole slots 32 to receive the heads of the posts 14, and slots 33 to receive the locking pin 16, just described. This pin is made of such length in order that it can be easily placed and removed, but if desired, it can be made somewhat shorter and the-slots 33 omitted. This lens 25 is held in position by small plates 35 on the rear side of the flange 31, the bolts 36 and nuts 37. The plates 35 are so thin that they may-be pressed into the cushion 18.

When the lens and its supporting ring are to be attached to the body, the ring is positioned so that the cylindrical portion 27 will smaller ends of the keyhole slots 32.

fit around the ring 10 of the body; the posts 14 enter the slots and the screw 10 enters one of the slots 33. The ring is then pressed against the rim 17 of theretiector, againstthe tension of the springs 12, until the heads of the posts 14 extend beyond the flange 31. The ring and lens are then turned (to the right in Fig. 3) until the posts 14 are in thp screw 40, mounted in a sleeve d1 between the parts 26 and 30 of the lens-supporting ring, can then be turned in until its inner end extends inwardly to the right of and beyond the adjacent post 14, as shown in Figs. 2, 3 and 5. This will prevent the ring and lens from being turned to the left. When the lens-supporting ring is thus positioned, it will. press against the cushion 18 sufficiently to compress the springs 12, as shown in Fig. 4. As a result, all rattling is obviated, and entrance of air and moisture prevented.

Instead of mounting the lens-supporting ring on the posts 14., it may be provided with lugs 15 which fit between the cars 46 on the body 47, as shown in Figs. 10 and 11. The parts 18 and 4-9 of the body 1 and lens-car rying ring near the line of the parts 46 and 47 may be at a slightly ditlerent angle than the parts 10 and 27 in the other form, or the same parts on the line 1212 of Fig. 10, and the posts 14 will be entirely omitted. The screws 13 position the springs 12 which hold out the reflector, which is connected to the body in the manner previously described. The rim may be pivoted permanently on one of the pins 50 or both of the pins can be re moved each time the lamp is to be opened. \Vhen the ring is hold in position by both pins, the reflector flange 20 will con'ipress the springs 12, as shown in. Fig. 18, tensioning them so that the cushion 18 will be so firmly pressed out against the flange 31 and the lens 25 that rattling of the parts becomes impossible, and entrance of air and moisture is prevented.
